IMPROVEMENT IN CARDlNG-ENGINES.

` Specification forming part of Letters Patenty No. 3,174, dated July12, 1843; antedated January 12, 1843.

To all whoml it may oon/cern..-

State of Connecticut, have invented a new; and useful Improvement inMachines for Carding and Roping Wool, Cot-ton, and other Fibrous Matter,which is described as follows, reference being had to the annexeddrawings of the same, making part of this specification.

Figure l is a side elevation of the machine. Fig. 2 is an elevation ofthe opposite side of the machine. Fig. 3 is aside elevation of thegearing of the condenser. Fig. 4 is a top or birds-eye view of the same.Fig. 5 is a section of the chain-belt for turning the workers. Fig. 6 isa section of the feed-gear; Fig. 7, the pitman and fingers for vibratingthe cylinders.

Similar parts refer to corresponding parts.

The frame of this machine, lettered A, is made of any suitable size,strength, and material for containing and supporting the several partshereinafter to be described.

The main cylinder B is made in the usual manner, about four feetdiameter, five feet in length, and coveredwith cards of the ordinarydescription, the proportions and dimensions of said cylinder to bevaried to suit the views of the manufacturer. It is supported on theframe by a main shaft C, passing through its center and turning in boxesin a metallic stand D, secured to the top of the frame A, being turnedby a band E, leading from the driving-power to the-main pulley F on thesaid main shaft C.

The arches G for supporting the puppetheads H, in which revolve theaxles I of the Workers K, strippers L, fancy M, and doffers N N2, aremade in the usual or most approved manner and firmly secured to the topof the frame A. On the axles of the workers K are cog-wheels O, overwhich is passed an endless chain belt P, made of leather or othersuitable material', having round or square apertures in the samecorresponding with the cogs of the cog-wheels, and also extended arounda cogwheel on the axle of the upper doffer N, from which it receives itsmotion, and which is simultaneously communicated to all the workers K, aband Q, Fig. 8, passing around the -main shaft C and around a pulley Ron the axle of a pinion S, working into the -cogwheels T T2 on the axlesof the upper and lower doffers N N2.

The strippers L and fancy M are revolved simultaneously in a contrarydirection to` the main cylinder B and the workers K by a belt Y, aboutthree inches wide, passed around the open pulley U on the main shaft C,outside of the frame A, and around the ten i or more pulleys V on theaxles of the ten or more strippers L, thence around a pulley W on ashaft turning in boxes on the sill of the frame A, and thence around thepulley X of the fancy M, thus formingan endless belt Y. The puppet-headsof the workers and strippers are arranged in pairs and are connected byright-and-left-hand screws for the purpose of setting them to or fromeach other.

The condenserl is made as follows: The standva, for containing andsupporting the condenser cylinder or cylinders b, vibrating cylinders Cc, and rollers d, is made of castiron or other suitable material, and issecured to the top of the frame Ain front of the condenser-doffers N N2.The condensing-cylinders b are composed of solid cylindrical bars ofiron about two inches in diameter, more or less, turning on gudgeons inpuppet heads or boxes f, supported on a horizontal arm g, projectingfrom the stand a, which cylinders are all to be covered with leather andturned off straight and true, revolving with their surfaces nearlytouching each other. i The vibrating cylinders C c are placed upon thesecondensing cylinders, and each having a bearing on twocondensing-cylinders, bywliich arrangement four bearing-points on theroping are obtained by three condensing-cylinders and two vibratingcylinders instead of -only two bearing-points, as heretofore, with threecylinders, said vibrating cylinders C c being made of wood covered withleather, and of the same diameter as. the condensingcylinders, havingsuitable iron axles on which the `said cylinders are formed, beingrevolved and vibrated in the usual manner, the vibration of thecylinders being effected by means of a pitman p, Fig. f7, attached to acrank-shaft of the usual kind situated on the sill of the frame, turnedby a belt q. The

rst condensing-cylinder b next to the doffer- V card N is placed withinabout one-eighth of an inch of the surface of the card, the top of itbeing about on a horizontal line with the center of said doffer-card,the surface having the same motion or speed, or more, than the card, forthe purpose of giving a slight draft on the roping, which draft may alsobe increased, if required, by gradually increasing the diameters of thesecond and third cylinders b, or by arranging the gearing to effect thesame object, any suitable number of said condensing-cylinders beingadded, if foundv advantageous in practice, which may also be graduatedin the manner before mentioned, and for a similar purpose. i

rlhe Wool, cotton,or other iibrous substance is taken from thedoffer-card N by the small roller d, in connection with the firstcondensing-cylinder h below the cylinder d, from which it receives itsmotion by being placed other'condenser-cylinders and vibrating cylindersplaced upon them, where the wool is condensed into roping. The movementsmay, however, be effected in various ways.

The axle of the small roller d is provided at each end with a smallset-screw s for adjusting its position in relation to the surface of thedofngcard N and said roller d should be of such diameter as to fill thespace between the doffer-card N and the first vibrating cylinder C.

The machine is fed at gin the usual manner.

What I claim as my invention, and which I desire to secure by LettersPatent, is-

l. Taking of the wool or roping from the JOHN BOYNTON.
